METHOD OF PRODUCING SEMIPERIVIANENT MARKINGS ON SILK FABRICS.

Application filed July 18,

'1 '0 all whom it may conceim:

Be it known that I, OWEN OSBORNE, a citizen of the United States, residing in the city and county of Philadelphia and State of Pennsylvania, have invented a new and useful Method of Producing bemipermanent Markings on Silk Fabrics, of which the following is a specification.

My invention relates to a novel method of producing a semi-permanent marking on textiles, particularly hosiery, and it relates more particularly to a method of embossing a name, legend or advertising symbol in a semi-permanent manner on the toe or other portion of hosiery, particularly silk hosiery.

To the above ends my invention consists of a novel method of producing a semipermanent marking, by embossing said marking in the fabric of the toe of a stocking, or the like by certain steps involving moisture, heat and pressure.

My invention further consists of a novel method of embossing and marking on the toes of hosiery, consisting in subjecting the surface of the fabric of said hosiery to the simultaneous action of moisture, heat and pressure over a pre-determined area as determined by the particular shape of the die employed, and for a pre-determined period thereby producing a hardened glossy surface over or at the portions affected and a normal surface over the portions unaffected by the pressure.

For the purpose of illustrating my invention I have shown in the accompanying drawings forms thereof which are at present preferred by me, since the same have been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described.

Figure 1 represents a plan view of a stocking embossed by the novel method embodying my invention.

Figure 2 represents a plan view of a press employed to carry out my invention.

Figure 3 represents a side elevation of the same.

Figure 4 represents on an enlarged scale a section on line 4-4 of Figure 2.

1924. Serial No. 726,723.

Figure 5 represents on an enlarged scale a plan view of a stocking embossed in accordance with my invention.

Figure 6 represents a perspective view'of the embossing die employed in carrying out my invention.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings 1 designates a stocking having a foot or toe portion 2 and a characteristic marking 3 thereon, embossed in a semi-permanent manner according to my invention.

In carrying out my invention the stocking 1 is placed upon a sheet of heavy paper or thin card board 4, and the die 5, With the engraved surface thereof moistened with water, is superimposed upon the toe 2 thereof, and the paper 4 carrying the stocking or a plurality of stockings 1 with the dies 5 superimposed thereon, is placed between two plates 6 and 7 of the press 8, as shown in Figure 4.

The plates 6 and 7 are hollow and are supplied with steam or other source of heat,v through the piping 9 so that the plate 6 serves as a heated bed, and the plate 7 as a heated pressure plate. The two plates 6 and 7 are now brought together by means of any pressure mechanism such as shown in Figure 3 and the stocking and die is thus held under pressure for a period of approximately three minutes, after which the pressure is relieved and the stockings and dies removed from the paper 4.

materialypreferably of a hard wood, such as maple, and the characteristic markings or letters 13 may be engraved into a smooth surface 12 thereof, as shown in Figure 6.

By my novel method of embossing silk stocking, I am enabled to produce any characteristic design, symbol marking or lettering on the toe or any other part of the stock- 7 ing, which willst-and out very clearly, and,

will be of an unusually attractive appearance, in which no foreign ingredient or material is employed to effect said visible marking, and the-inarking' thus produced hosiery without the aid of any foreign maoriginal strength, andluster of the fabric. The elements for simultaneously applying stocking may be variously constructed. In

,terial or /ingredients and Without in any way harming the fabric .or decreasing the statement of the invention and the above description, andzyvhile I hare; i;n-;the present instance, shown and described'a preferred embodiment thereof which will give in practice satisfactoryand reliableresults, it is to beunderstood that thesame--is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any' of its advantages.

Having thus described my invention what I claim as new and, useful and desire to se cureby Letters Patent, is
